2011-06-21ARM: 6961/1: zImage: Add build-time check for correctly-sized proc_type entriesDave Martin1-1/+13
It is easy to mis-maintain the proc_types table such that the entries become wrongly-sized and misaligned when the kernel is built in Thumb-2. This patch adds an assembly-time check which will turn most common size/alignment mistakes in this table into build failures, to avoid having to debug the boot-time kernel hang which would happen if the resulting kernel were actually booted.

2011-06-17ARM: 6963/1: Thumb-2: Relax relocation requirements for non-function symbolsDave Martin1-2/+11
The "Thumb bit" of a symbol is only really meaningful for function symbols (STT_FUNC). However, sometimes a branch is relocated against a non-function symbol; for example, PC-relative branches to anonymous assembler local symbols are typically fixed up against the start-of-section symbol, which is not a function symbol. Some inline assembler generates references of this type, such as fixup code generated by macros in <asm/uaccess.h>. The existing relocation code for R_ARM_THM_CALL/R_ARM_THM_JUMP24 interprets this case as an error, because the target symbol appears to be an ARM symbol; but this is really not the case, since the target symbol is just a base in these cases. The addend defines the precise offset to the target location, but since the addend is encoded in a non-interworking Thumb branch instruction, there is no explicit Thumb bit in the addend. Because these instructions never interwork, the implied Thumb bit in the addend is 1, and the destination is Thumb by definition. This patch removes the extraneous Thumb bit check for non-function symbols, enabling modules containing the affected relocation types to be loaded. No modification to the actual relocation code is required, since this code does not take bit[0] of the location->destination offset into account in any case. Function symbols are always checked for interworking conflicts, as before.

This patch updates the board specific USB support code for the sh7372 Mackerel board. With this patch applied port CN22 is driven by the recently added renesas_usbhs driver using the first USB controller included in sh7372 aka USBHS0. Hotplugging of USBHS0 unfortunately has to be handled by software polling. The sh7372 SoC itself obviously supports hotplug notification by IRQ but on the Mackerel board this IRQ happens to be used for the touch screen.

2011-06-09Revert "ARM: 6943/1: mm: use TTBR1 instead of reserved context ID"Russell King2-10/+11
This reverts commit 52af9c6cd863fe37d1103035ec7ee22ac1296458. Will Deacon reports that: In 52af9c6c ("ARM: 6943/1: mm: use TTBR1 instead of reserved context ID") I updated the ASID rollover code to use only the kernel page tables whilst updating the ASID. Unfortunately, the code to restore the user page tables was part of a later patch which isn't yet in mainline, so this leaves the code quite broken. We're also in the process of eliminating __ARCH_WANT_INTERRUPTS_ON_CTXSW from ARM, so lets revert these until we can properly sort out what we're doing with the ARM context switching.
